An intermolecular force is an attractive force that develops between the protons or positive parts of one molecule and the electrons or negative parts of another molecule. The kinetic energy keeps the molecules apart and moving around, and is a function of the temperature of the substance and the intermolecular forces try to draw the particles together Intermolecular Forces Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. 2 Intermolecular force Intermolecular forces exist between molecules rather than within them. London dispersion forces exist between all molecules. They are attracting forces and therefore are much weaker than molecular bonds, which are created by intramolecular forces, or forces within molecules. In liquids, the forces are weaker, allowing particles to slide past each other. 1: Interactions between Molecules All substances experience dispersion forces between their particles. Flask C shows the most particles in the vapor phase.
